Adinary Nuance

A mouse is the common word for the small animal, but it can also mean the computer device. If you mean the device, most writers say computer mouse or just mouse in tech contexts. It is not the same as rat, which is usually larger and less cute. In formal writing, mouse is still fine because both meanings are standard.
